Sotsugyou ** Densha

A great, high quality animation full of solid shortstack action, however the story is rather confusing.
Any time he does anything to her it seems to reset, you're constantly unsure whether things are real or just in his head.

However, as an adaptation you can argue that this fails spectacularly, because of just how much it changes.
In the original comic it's a dude lusting after a schoolgirl that proceeds to molest her on the train, in this it's a story about a kid who was doing lewd stuff with his teacher (which we see some scenes of), and now he's an adult and encounters another teacher on ... the train that is identical to that one for some unexplained reason, and proceeds to imagination-molest her.
If this was a typical anime, the fanbase would be rioting over so many changes, so it's better to take them as standalone works and enjoy both.

overall, if you wanna enjoy some shortstack action without thinking about the plot - definitely give it a try.

This hentai shows a new typo of animation that I have not seen before, That is the reason why I chose a score of two because the good animation, if the animation was older I would porbably have chosen one. So despite it has a new animation that I would love to see in another hentai more enjoyable, this hentai is discusting, it just shows how a dirt mind violates a woman over and over again. Of course she didn;t enjoy it and thats what make it gross, normalizing violent acts to woman just to make a man feel pleasure.
